i dont think sysgen's problem is related to cccp's. my car at idle when warmed up will hang around 2 bar. then driving 5 bar. i think that it is just one of those normal occurences. but the tach never bounces as well.

Sysgen

Well total mystery, used the car all day and it didn't do it once

Thanks Fishey, but what is the ICV and the reference sensor and where are those located and what do they do?
